摘要
Abstract

The homogeneity between the high-and low-affinity glucocorticoid receptors(GR
H
and GR
L
)was testified by immunoaffinity chromatography using Mab N250(recognizing the immunogenic domain at the N terminal of GR
H
)and Mab BuGR1(recognizing the DNA binding domain of GR
H
).The specific binding peak of 0.98μmol/L[
3
H]triamcinolone acetonide(TA)was higher than that of 52.50nmol/L[
3
H]TA.The re-sult suggests that the antigenic determinants of GR
L
are similar to those of GR
H
.ThecDNA of rat liver GR
H
was introduced into GR
H
-and GR
L
-negative mouse fibroblast cellline E82.A3 by calcium phosphate coprecipitation.A number of clones which expressGR
H
were selected with G418(400μg/ml).The results of radioligand binding assay indicatethat GR
H
gene is expressed successfully and GR
L
also may be encoded by GR
H
gene.
